Age estimates on Clovis, Late Paleoindian, and Archaic components were obtained using Received in revised form 10 March 2016 optically stimulated luminescence (OSL) dating of silt-sized quartz grains. The luminescence characteristics of Accepted 11 March 2016 the quartz are favorable, showing normal equivalent dose distributions and no evidence of incomplete zeroing. Available online 12 April 2016 The artifacts span Clovis to Archaic forms, and their ages are generally in excellent agreement with independent radiocarbon ages from five other Texas sites.
